<P>PROBLEM TO BE SOLVED: To acquire image data in which background tissue outline is sufficiently reduced. <P>SOLUTION: Data S<SB POS="POST">1</SB>(k<SB POS="POST">x</SB>, K<SB POS="POST">y</SB>) of a k-space of an imaging region is collected by scan SC<SB POS="POST">non</SB>without a contrast agent, and data S<SB POS="POST">2</SB>(k<SB POS="POST">x</SB>, k<SB POS="POST">y</SB>) of k-space in which the contrast of the artery is emphasized are collected by scan SC<SB POS="POST">ca</SB>with a contrast agent. Image data of the artery are calculated using a difference ¾S<SB POS="POST">2</SB>¾-¾S<SB POS="POST">1</SB>¾ of absolute values of the k-space and a phase S<SB POS="POST">2</SB>/¾S<SB POS="POST">2</SB>¾ of the k-space. By using the difference ¾S<SB POS="POST">2</SB>¾-¾S<SB POS="POST">1</SB>¾ of absolute values of the k-space and the phase S<SB POS="POST">2</SB>/¾S<SB POS="POST">2</SB>¾ of the k-space, the outline of the background tissue hardly remains. <P>COPYRIGHT: (C)2012,JPO&INPIT |
